Understanding Low Creatinine Levels

Creatinine is a waste product produced by muscle metabolism. Low creatinine levels (below 0.6 mg/dL) may indicate reduced muscle mass or other underlying health conditions.

What is Considered Low?

A creatinine level below 0.6 mg/dL is considered low. While low creatinine is not always a concern, it may indicate:

  • Reduced muscle mass
  • Malnutrition
  • Liver disease
  • Pregnancy
  • Aging

Common Symptoms

  • Weight loss
  • Reduced exercise capacity
  • Poor appetite

Metabolic Symptoms

  • Slow metabolism
  • Difficulty gaining muscle
  • Poor wound healing
  • Reduced immune function

Systemic Symptoms

  • General weakness
  • Poor endurance
  • Difficulty maintaining weight
  • Reduced physical performance

Causes

Primary Causes

  • Muscle wasting conditions
  • Malnutrition
  • Liver disease
  • Advanced age

Diagnosis

The diagnosis of low creatinine involves:

  1. Medical history review
  2. Physical examination
  3. Blood tests including:
    • Serum creatinine
